Specification of Letters Patent.

Application filed April 2'7, 193.6.

To all whom it may concern:

Be it known that I, ARTHUR W. DUDLEY, a citizen of the United States,residing at Marlboro, in the county of Middlesex and tate ofMassachusetts, have invented cer tain new and useful Improvements inEdge- Guide Attachments for Sewingdslachines; and do hereby declare thefollowing to he a full, clear and exact description of the inventi 11such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to an edge guide attachment for sewing machineswhich are used in the fitting room of a shoe making establishment, inthe operation of top stitching of shoes and the primary object of theinvention is to provide an attachment specified which is constructed sothat it will be simple and easy for the operator to keep on the edge onthe top of the upper of the shoe and thereby get an even regular line ofstitching insuring good and uniform work.

Another object of this invention is to provide an attachmeit or guide asspecified which can be instantly thrown out of an operative position thewill of the operator, should shoe being worked upon require a bar or roforcement of any kind on the strap and which when thrown into aninoperative position will permit of a clearance of practically two andone-half inches so that it will not in any way bother the operator ofthe machine A further object of this invention is to provide a guide asspecified which is constructed for allowing the needle to run as closeto the edge of the top of the shoe as the operator may desire.

ll ith the foregoing and other objects in riew this invention consistsin such novel features of construction, combination and arrangement ofparts will he hereinafter more fully described, illustrated in thecompanying drawing and claimed.

In describing the invention in detail reference will he had to theaccompanying drawing wherein like characters designate like PatentedApr. 2a, 1917.

It i g. 2 is an end view of the guide.

Fig. 3 is a top plan View of the guide showing the same swung into aninoperative position, and

Fig. l is a cross section through the guide.

Referring more particularly to the drawing, 1 designates the base orattaching plate of the guide which is provided with a slot 2 and agroove 3 which extends inwardly from one end of the plate and is adaptedfor receiving a boss 4: which projects downwardly from the under surfaceof the pivoted supporting block 5. The supporting block 5 is pivotallysupported by a pin 6 which is attached to and projects'upwardly from theuppersurface of the attaching plate 1. The block 5 is mounted upon thepin 6 for vertical movement "ith respect thereto, and a spiral spring 7is coiled about the pin and engages the upper surface of an arm 8 whichis mounted upon the upper surface of the block 5 and the under surfaceof a washer 9 which washer is mounted upon the pin 6 and is held inplace by means of a cotter pin or the like 10. The spring 7 tends toforce the under surface of the block 5 in engagement with the uppersurface of the attaching plate 1. at all times and it also forces theblock downwardly so that the boss 4 will be seated in the groo e 3, whenthe attachment is in .an operative position for preventing accidentalrotary movement of the block and the structure carried thereby.

A cam 1]. is pivotally connected to the lolock 5 as shown at 12 and ithas a thumb piece 13 formed thereon, by means of which the cam isrocked. The cam 11 is provided with a rounded shoulder 14 which engagesthe upper surface of the attaching plate 1 so that when the thumb handleor rest 13 is moved downwardly, the rounded shoulder 14 will ride uponthe upper surface of the plate 1 and force the block 5 upwardly out ofengagement with the upper surface of the plate 1 so as to permit theblock to he swung into a transversely extending position as illustratedin Fig. 3 of the drawing. A pin 15 is carried by the attaching plate 1and it limits the pivotal movement of the block 5.

The arm 8 is provided with an opening 17 formed therein, which openingreceives the rolled end 18 of a guide arm 19. A pin 20 extends throughthe rolled end 18 and through the plate 8 for pivotally connecting theguide arm 19 to the guide arm 8. The arm 19 is provided with a slot 21formed therein which receives a guide pin 22 carried by the arm 8adjacent to its outer end. A set or thumb screw 23 is threadably carriedby the guide arm 19 and its under or inner end engages the upper surfaceof the guide arm 8 for holding the arm 19 in various adjusted pivotalpositions with respect to the arm 8. A spiral spring 24c is coiled aboutthe thumb screw 23 and engages the upper surface of the guide arm. I

A spring or resilient wire 25 has one end attached to the upper surfaceof the arm 8 by means ofa screw 26 and its other end extendingtransversely across and engaging the ppper surface of the arm 19 asshown at 2 The outer end of the guide arm 19 is bent downwardly as shownat 28, and further as shown at 29 to provide a portion 30 which extendssubstantially at right angles to the surface of the plate 1 and also thearm 8. The outer surface of the transversely extending portion 80 isprovided with a groove 31, which forms a guide for the needle of thesewing machine when the guide is adjusted so that the article beingsewed will be stitched very close to its edge.

The edge guide is adjustably attached to the table A of a sewing machineby means of thumb screws B which extend through the slot 2 and theangled end 30 of the guiding arm 19 is positioned so that the edge ofthe article being sewed will engage the outer surface of the angled end30, thereby maintaining a uniform distance between the edge of thearticle being sewed and the needle C of the sewing machine. Thedistancebetween the end 30 and the needle C may be varied as desired byloosening the thumb screws B and sliding the attaching plate 1 eithertoward or away from the needle C as desired.

Then it is necessary to sew inwardly from the edge of the article beingworked upon, the cam 11 is rocked through the medium of the thumb piece13 and the block 5 is rotated or swung about on the pin 6 forpositioning the guiding arm 19 and the plate 8 at right angles to theirnormal operative positions.

From the foregoing description taken in connection with the accompanyingdrawing, the advantages of construction and of the method of operationof the improved edge guide attachment for sewing machines will bereadily apparent to those skilled in the art to which this inventionappertains, and while in the foregoing description, the principle of theoperation of this invention has been described together with variousfeatures of construction, it is to be understood that certain minorfeatures of construction, combination and arrangement of parts may bealtered to suit practical conditions'provided such alterations arecomprehended within the scope of what is claimed.
